Practice Test 1 CCRN (Pass CCRN)
Exam Questions and Verified Detailed
Answers | Graded A+
What is vasogenic cerebral edema? - ✔✔Vasogenic cerebral edema is an
increase in extracellular fluid caused by a breakdown of the blood-brain
barrier with the resultant increase in vascular permeability. This cerebral
edema begins locally and becomes more generalized. Common causes are
trauma (including surgical trauma), tumors, hemorrhage, and abscesses
What ventilator parameter indicates fluid volume excess? - ✔✔An A:a
gradient greater than 10 mm Hg is a reflection of a diffusion defect. Note
that the process of diffusion is between A (alveolus) and (a) arterial blood.
An increase in intraalveolar fluid dilutes and inactivates surfactant, causing
alveolar collapse (decreasing vital capacity) and decreases lung
compliance. Peak inspiratory pressure increases reflect a decrease in lung
compliance

,What does autonomy refer to? - ✔✔The patient's right to make decisions
for themselves
What does beneficence mean? - ✔✔Obligation to do good
What does nonmaleficence mean? - ✔✔Obligation to do no harm
What does fidelity mean? - ✔✔the obligation to abide by agreements and
responsibilities
What does veracity mean? - ✔✔The obligation to tell the truth
What are Diagnosis-Related groups? - ✔✔DRGs constitute a prospective
payment program for Medicare patients. Payment is based on primary and
secondary diagnosis, primary and secondary procedures, age, and length
of hospitalization
BNP is secreted in response to? - ✔✔Ventricular wall stretch
What are omnious signs in a patient with status asthmaticus? - ✔✔A
normalization or increase in the PaCO2. This patient is still tachypneic, and
if ventilation is normal, PaCO2 should be decreased. The other ominous
sign in this patient would be absence of wheezing or rhonchi, because they
would indicate that ventilation is insufficient to cause these noises.

, What problems arise from losses from the GI tract? - ✔✔Any loss results in
hypokalemia. Vomiting results in loss of acidic contents, whereas losses
below the pylorus result is alkalitic losses leading to metabolic acidosis.
Fluid is sequestered in the intestine leading to hypovolemia, which could
cause hypovolemic shock.
Actual problems are worse than potential problems!! - ✔✔
How can you differentiate the cause of jaundice? - ✔✔An increase in direct
bilirubin is associated with biliary obstruction because direct bilirubin is
conjugated. An increase in indirect bilirubin is associated with hepatic
disease or excessive hemolysis because indirect bilirubin is unconjugated
What antihypertensive meds work best in African american patients? -
✔✔African-Americans do not respond well to angiotensin-converting
enzyme inhibitors (e.g., captopril [Capoten]), but they do respond well to an
angiotensin II blocker (valsartan [Diovan]). Of the beta-blockers, labetalol
works best. Of the calcium channel blockers, diltiazem works best
What lab values define acute respiratory failure? - ✔✔50-50!
PaO2<50 and/or PaCO2>50
Hyperkalemia can cause what? - ✔✔Diarrhea-increases gastric motility
